LAMP.

Specification of Letters Patent.

Patented March 9, 1909.

Application filed August 6, 1906. Serial No. 329,367.

` To all whom it may concern:

Be it known that I, FAULUs HEYLANDT, a subject of the King of Prussia,and a resident at larthauserstrasse 65, Erfurt, Germany,

have invented an Improved Lamp, of which the following is a full, clear,and complete specification.

The present invention relates to improvements in lamps or the like, ofthe type in 10 which the vapor of a suitable combustible is generatedand intimately mixed with gaseous oxygen generated from liquid oxygen orliquid air, said improvements being particularly applicable to solderingor Welding l5 lamps of the above type as they enable such to bemanufactured in a form very suitable for mounting or iitting purposes.Said improvements are also especially applicable to lamps of the abovetype used for illumination when such lamps are required to be in a veryhandy form and to be comparatively light in weight, as for example, whenthey are for use on vehicles or' all kinds.

The objects of the improvements are to increase the safety of such lampsand to facilitate their regulation and to improve their efficiency byarrangements which guarantee the intimate mixing of the combustible andoxygen on issuing from their respective outlets. Y

The improvements have as a further object to increase the durability ofsuch lamps.

The improvements consist of the arrangements, dispositions andcombinations of parts hereinafter set forth and claimed.

The accompanying drawing illustrates a lamp embodying the improvementsaccording to the present invention.

In said drawings Figure l is an elevation of the lamp, the burner beingshown in cross section: Figs. 2 and 3 are transverse sections of adetail of Fig. l in different positions.

In Fig. l a receptacle A mounted firmly on a base IV and provided with ahandle Y is shown, which receptacle serves for containing the liquidcombustible, for example, benzin. An ordinary lamp E is under the samefor supplying the necessary heat to the receptacle A in order tovaporize the liquid combustible therein. The gaseous combusltible flowsout of the receptacle A in a plurality of pipes c, c, a, arrangedaxially inside l the burner l, in order to escape at the end of thesame.

The vessel B of a suitable kind for liquid air or liquid oxygen, whichis preferably provided with ribs or other means for increasing I theouter surface in order to secure a su'llicient evaporation, is mountediirmly on the i base E? and is fastened by means of' a wrought ironstrap Z or the like to the burner l and supplies oxygen to the benzinflame in the same through the pipe Z). This pipe b runs in the firstplace in a helix o", to around the mouth of the burner and then alongthe same and goes inside the burner 1 in several branch pipes 61, b1,parallel to the benzin pipes a, c, c, and the gaseous oxygen comingdirectly from the liquid oxygen in the vessel B on leaving the pipes b1,b1, intimately mixes with the benzin vapor escaping from the pipes a, c,a. In this manner the greatest heat is developed at the mouth of theburner. But in consequence of the arrangement of the pipes and burner,the very cold gaseous oxygen coming from the vessel B protects theburner at its mouth from the damaging effect of the very great heat, asthe cold oxygen circulates around the burner l through the helix b", bo.At the same time a suitable Warming of the oxygen to be supplied to theflame takes place beforehand.

In order to assure a supply oi oxygen corresponding at all times to theconsum. tion of the same and to regulate the supp y, a three-way valveor tap O is arranged above the vessel B which can be set by hand. Thepurpose of this tap C is to be seen in Figs. 2 and 3. Fig. 2 shows theconnection of the vessel B by way of 1,2 with the pipe b, while in Fig.3 the shutting oil of this connection is shown but here, on thecontrary, the way 3, l to the open air is open, through ,vhich the airescapes which develops in the vessel B owing to the gasi'cation which isalways taking place even if very slightly.

lil/hat I claim as my invention and desire to secure by Letters Patentis z- 1. In a lamp of the type described, the combination with areceptacle for liquid combustible, of means for heating said receptacleto evaporate the combustible, a vessel for containing a liquid supporterof combustion, a tubular burner supported by said vessel, a plurality ofparallel pipes in said I I l burner, a pipe connecting` one part of saidpipes at the internal end of said burner with said receptacle, andanother pipe connecting the other part of said pipes at the internal endof said burner with said Vessel while surrounding in several turns theexternal end of said burner so as to cool saine with the gasiiiedsupporter of combustion.

2. ln a lainp of the type described, the combination with a receptaclefor liquid coinbustible, oi a lamp for heating` said receptacle toevaporate the combustible, a Vessel 'for containing a liquid supporterof Cornhustion, a support on said Vessel, a tubular burner secured insaid support, a plurality of parallel pipes in said burner and ter*ininating at a distance from the external end I of sa1ne,.a pipeconnecting one part of said pipes at the internal end of said burnerwith said receptacle, and another pipe connecting the other part of saidpipes at the internal end of said burner with said vessel Whilesurrounding in several turns the external end of said burner so as tocool saine with the gasiiied supporter oi' combustion.

3. ln a lanip of the type described, the combination with a receptacleJfor liquid combustible, of ineansfor heating said receptacle toevaporate the combustible, a Vessel for containing a liquid supporter ofcombustion, a tubular burner supported by said vessel, a plurality ofparallel 'pipes in said burner, a pipe connecting one part oi said pipesat the internal end of said burner with said receptacle, a second pipeconnecting the other part of said pipes at the internal end of saidburner with said vessel While surrounding in several turns the externalend of said burner so as to cool saine with the gasiiied supporter ofcombustion, and a Valve inserted in said second pipe and adapted to turnon the gasiiied supporter of combustion to the burner for use and toturn it ofi to the ambient air When not in USB.

1l. ln a lainp oi the type described, the combination With a receptaclefor liquid combustible, oi' a lamp for heating said receptacle toevaporate the combustible, a

vessel'i'or containing a liquid supporter of combustion, a support onsaid Vessel, a tubular burner secured in said support, a plurality ofparallel pipes in said burner and terminating at a distance from theexternal end of saine, a pipe connecting one part of said pipes at theinternal end of said burner with said receptacle, a second pipeconnecting the other part of said pipes at the inter'- nal end of saidburner With said Vessel While surrounding in several turns the externalend of said burner so as to cool saine with the gasiiied supporter ofcombustion, and a valve inserted in said second pipe and adapted to turnon the gasiiied supporter oi combustion tothe burner for use and to turnit ofi to the ambient air When not in use. Y

ln testimony whereof I have signed niy naine to this speciiication inthe presence oi the two subscribing' Witnesses.
